4-Port Fiber Circulators
Description
The 4-port circulators are based on faraday rotator. It's a non-reciprocal device so that the circulator can protect the optical source from the backward propagating light signal.

Frequently Asked Questions
A 4-port fiber circulator is a non-reciprocal device based on faraday rotator that protects the optical source from backward propagating light signal.
The features of a 4-port fiber circulator are isolation of more than 40dB, insertion loss of less than 1.0dB, and the ability to be combined with fiber splitter or fiber coupler in one module to save cost and space.
The applications of a 4-port fiber circulator are bi-di transmission, fiber sensor, OTDR instrument, and dispersion compensation.
A polarization insensitive circulator is used for routing light path and is widely used in sensing communication systems. It features low insertion loss, high cross talk, and high reliability and stability.
The specifications of a polarization insensitive circulator include operating wavelength range, insertion loss, polarization dependent loss, polarization mode dispersion, isolation, directivity, return loss, power handling, pigtail length, port color, tensile load, operating temperature, and storage temperature.
